Jsx never achieves plain-old-html in my view. <div /> is legal but <br> isn't.

  <br /> is which matches xhtml (if not html5)

    Html 5 has displaced XHTML for decades. And notably, XHTML is not html. <br /> is valid html5, but the trailing slash is meaningless. In JSX, it's required.

      XHTML5 is a thing.

        This is news to me. From what I can find (which is not much), it seems like XHTML5 is a further constraint on HTML5. So legal XHTML5 is legal HTML5. https://en.wikipedia.org/wiki/HTML5#XHTML_5_(XML-serialized_HTML_5) https://en.wikipedia.org/wiki/HTML5#XHTML_5_(XML-serialized_... If that's true, that means <div /> is not valid XHTML5 because 1) trailing slashes don't close tags in html and 2) div elements require a closing tag. And if that's true, then it's still different from JSX. But this XHTML5 thing might be surpassing my comprehension.
